Beyond Obesity and Overweight: The Clinical Assessment and Treatment of Excess Body Fat in Children : Part 1 - Insulin Resistance as the Root Cause of Pediatric Obesity

PURPOSE OF REVIEW

Pediatric obesity and comorbidities related to insulin resistance continue to be a growing public health crisis. If lifestyle measures are unsuccessful, pharmacological and surgical interventions are offered. In this paper, we describe the driving force of the obesity crisis: hyperinsulinemia and the development of insulin resistance. We give historical background of key policy issues which have contributed to this pandemic as well as the physiologic mechanisms of insulin resistance. The prevalence of obesity will continue to rise unless the root cause of hyperinsulinemia is addressed.

RECENT FINDINGS

Current research on insulin resistance demonstrates that a decreased consumption of carbohydrates is an effective first-line dietary intervention for the treatment of obesity and related metabolic diseases. Evidence shows it is safe and beneficial. A low-carbohydrate eating pattern can be helpful to address pediatric obesity. However, there must be policy guardrails in place to ensure that this is a sustainable and viable option for children and their families. There must be a change in the nutritional environment to help individuals battle the chronic disease of obesity.

Adolescent cancer prevention in rural, pediatric primary care settings in the United States: A scoping review

Adolescence is a critical period for establishing habits and engaging in health behaviors to prevent future cancers. Rural areas tend to have higher rates of cancer-related morbidity and mortality as well as higher rates of cancer-risk factors among adolescents. Rural primary care clinicians are well-positioned to address these risk factors. Our goal was to identify existing literature on adolescent cancer prevention in rural primary care and to classify key barriers and facilitators to implementing interventions in such settings. We searched the following databases: Ovid MEDLINE®; Ovid APA PsycInfo; Cochrane Library; CINAHL; and Scopus. Studies were included if they reported on provider and/or clinic-level interventions in rural primary care clinics addressing one of these four behaviors (obesity, tobacco, sun exposure, HPV vaccination) among adolescent populations. We identified 3,403 unique studies and 24 met inclusion criteria for this review. 16 addressed obesity, 6 addressed HPV vaccination, 1 addressed skin cancer, and 1 addressed multiple behaviors including obesity and tobacco use. 10 studies were either non-randomized experimental designs (n = 8) or randomized controlled trials (n = 2). The remaining were observational or descriptive research. We found a dearth of studies addressing implementation of adolescent cancer prevention interventions in rural primary care settings. Priorities to address this should include further research and increased funding to support EBI adaptation and implementation in rural clinics to reduce urban-rural cancer inequities.

Appraisal of Clinical Care Practices for Child Obesity Treatment. Part I: Interventions

The objective of this technical report is to provide clinicians with evidence-based, actionable information upon which to make assessment and treatment decisions for children and adolescents with obesity. In addition, this report will provide an evidence base to inform clinical practice guidelines for the management and treatment of overweight and obesity in children and adolescents. To this end, the goal of this report was to identify all relevant studies to answer 2 overarching key questions: (KQ1) "What are clinically based, effective treatments for obesity?" and (KQ2) "What is the risk of comorbidities among children with obesity?" See Appendix 1 for the conceptual framework and a priori key questions.

Effectiveness of a Primary Care-Based Pediatric Weight Management Program

BACKGROUND

Childhood obesity is a growing epidemic of great concern for our nation, including pediatric populations treated at military treatment facilities.

OBJECTIVE

This study aims to retrospectively evaluate the effectiveness of a primary care-based structured weight management program in a sample of pediatric patients with obesity at a military treatment facility.

METHODS

This study was a retrospective chart review of patients enrolled in the All About Me Program (AAMP) from August 1, 2011, through July 10, 2012. Baseline demographics, 5-2-1-0 behavioral targets, and anthropometric measures were obtained from 54 enrollees. Pre- and post-program weight, body mass index (BMI) percentile, and 5-2-1-0 behavioral targets were compared for 20 patients who completed the program which consisted of a total of five visits over 3 months.

RESULTS

Participants showed a significant reduction in their BMI, improvement in daily servings of fruits and vegetables, reduction in recreational screen time from baseline, improvement in daily physical activity, and reduction in consumption of sugary beverages.

CONCLUSIONS

These preliminary findings are a promising indicator that primary care-based obesity interventions may be effective for the management and treatment of pediatric obesity.

IMPLICATIONS FOR NURSING

This evidence-based toolkit provides a practical point-of-care guidance on the prevention, assessment, and treatment of childhood obesity and can be easily implemented in other primary care settings.

Improvement in Primary Care Provider Self-Efficacy and Use of Patient-Centered Counseling To Address Child Overweight and Obesity after Practice-Based Changes: Texas Childhood Obesity Research Demonstration Study

BACKGROUND

The Texas Childhood Obesity Research Demonstration project, a multicenter, multisystem approach to childhood overweight and obesity (OW/OB), included training and materials to support primary care clinics (PCCs) in addressing child OW/OB in the office. This study evaluated the impact over 24 months of brief training and practice-based support on primary care providers' (PCPs) perceived self-efficacy and practice behaviors.

METHODS

The PCPs at five Houston and seven Austin PCCs completed questionnaires at baseline (2012, n = 36), 12 months (2013, n = 30), and 24 months (2014, n = 34) follow-up. Mixed-effects linear regression models were used to compare changes in self-efficacy (15 items, responses 1-4: not at all confident to very confident) and practice behaviors (30 items, responses 0-4: never to always) in obesity-related screening and counseling, and to assess association between prior training and these outcomes.

RESULTS

Self-efficacy items for identification of (2.9 [0.1] vs. 3.3 [0.1]) and counseling about (2.8 [0.1] vs. 3.4 [0.1]) OW/OB-related parenting practices, and setting behavioral goals (2.9 [0.2] vs. 3.3 [0.2]) improved significantly (p < 0.05) between baseline and 24-month follow-up. Self-efficacy items with "confident" mean baseline scores that further improved included determining child OW/OB (3.6 [0.1] vs. 3.9 [0.1]) and interpreting BMI (3.6 [0.1] vs. 3.9 [0.1]). At all measurements, PCPs reported frequently addressing medical problems and lifestyle behaviors. Use of patient-centered counseling techniques, which was low at baseline, increased significantly, including asking permission before discussing lifestyle (1.5 [0.3] vs. 2.4 [0.3]). Prior training was associated with improved self-efficacy.

CONCLUSIONS

The improvement in PCPs' self-efficacy and patient-centered counseling to address childhood OW/OB supports implementation of brief training and practice support in clinics that serve Medicaid-eligible children.

Adherence to sleep guidelines reduces risk of overweight/obesity in addition to 8-5-2-1-0 guidelines among a large sample of adolescents in the United States

OBJECTIVES

To examine whether adherence to US sleep, dietary, screen time, and physical activity (8-5-2-1-0) guidelines is associated with reduced risk of overweight/obesity in adolescents.

DESIGN

Multivariable log-binomial regressions were estimated using the 2017 Youth Risk Behavior Surveillance System data.

RESULTS

Of the 8194 adolescents aged 13 years and older, only 0.6% (49) met all guidelines. Meeting the recommended 8 hours of sleep per day was associated with reduced risk of overweight/obesity (risk ratio [RR]: 0.90; confidence interval [CI]: 0.81-0.99). Having ≤2 hours of screen time per day was associated with reduced risks of overweight/obesity (RR: 0.85; CI: 0.77-0.95). One hour of daily physical activity was associated with reduced risk of overweight/obesity (RR: 0.80; CI: 0.73-0.87). No significant associations were found between daily consumption of ≥5 fruits and vegetables or consumption of zero sugar-sweetened beverages and overweight/obesity. The 8-5-2-1-0 constitutes an improved prediction model to explain the risk of overweight/obesity among adolescents compared with the 5-2-1-0 model (F_1,36 = 4.80; P = .035).

CONCLUSIONS

Findings from this study suggest that meeting recommendations for sleep, screen time, and physical activity is associated with decreased risk of overweight/obesity in a large sample of adolescents. These are important factors to consider in the prevention and treatment of overweight/obesity in adolescents.

Tailored communications for obesity prevention in pediatric primary care: a feasibility study

Recommendations for the prevention of childhood obesity encourage providers to counsel parents and their children on healthy diet and activity behaviors. This study evaluated the feasibility of a theory-based, tailored communication intervention for obesity prevention (Team Up for Health) delivered during a well-child visit. A two-armed randomized controlled trial was used. Parents of children aged 4-10 years were recruited from a list of patients due for a well-child visit at a pediatric primary care clinic. Parents were randomized to either the 'immediate' condition (parent and pediatrician received the tailored report at the well-child visit) or the 'delayed' condition (parent received the report at the end of the study). Self-report measures assessed physical activity, fruits, vegetables, television time, sugary drinks, and 100% fruit juice. Parents completed assessments at baseline, <48 h and 4-week follow-up. Providers were interviewed at the end of the study. Independent t-tests were used to examine between group differences. Seven areas of feasibility were evaluated: Recruitment, randomization, measurement, retention, acceptability, implementation and demand. Results showed high rates of measurement (85%) and acceptability (89%) and implementation (80%) of the intervention. In conclusion, Team Up for Health was feasible; however, a larger study is needed to evaluate its efficacy.

Attainment of '5-2-1-0' obesity recommendations in preschool-aged children

Obesity prevention guidelines recommend children eat ≥ 5 servings of fruits and vegetables, view ≤ 2 h of screen time, participate in 1 h of physical activity, and consume 0 sugar-sweetened beverages daily, commonly known as '5-2-1-0'. We sought to determine: the extent to which preschool-aged children attending child care meet these guidelines, predictors of attainment, and associations of attainment with weight status. We analyzed in 2016, 24-hour dietary, physical activity, and screen time data collected in 2009-10 from 398 preschool-aged children in 30 child-care centers in Cincinnati, OH. Dietary intake, screen time and body-mass index (BMI) were obtained by research staff during child care and from parents when at home. Accelerometers measured physical activity. Mixed-effects models and generalized estimating equations were used to determine associations between '5-2-1-0' recommendations, demographic variables, and BMI z-scores. Average child age was 4.3 ± 0.7 years; 26% had a BMI ≥ 85th percentile. Seventeen percent of children with complete dietary data (n = 307) consumed ≥ 5 servings of fruits and vegetables and 50% consumed 0 sugar-sweetened beverages. < 1% with complete physical activity data (n = 386) met the activity recommendation; 81% of children (n = 379) had ≤ 2 h of screen time. Only 1 child met all of the '5-2-1-0' recommendations. There were no consistent demographic predictors of attaining individual recommendations. An additional hour of screen time was associated with a 0.11 (SD 0.06) increase in BMI z-score. Our data suggests there is ample room to increase fruit and vegetable intake and physical activity in preschool-aged children.

Brief Primary Care Obesity Interventions: A Meta-analysis

CONTEXT

Although practice guidelines suggest that primary care providers working with children and adolescents incorporate BMI surveillance and counseling into routine practice, the evidence base for this practice is unclear.

OBJECTIVE

To determine the effect of brief, primary care interventions for pediatric weight management on BMI.

DATA SOURCES

Medline, CENTRAL, Embase, PsycInfo, and CINAHL were searched for relevant publications from January 1976 to March 2016 and cross-referenced with published studies.

STUDY SELECTION

Eligible studies were randomized controlled trials and quasi-experimental studies that compared the effect of office-based primary care weight management interventions to any control intervention on percent BMI or BMI z scores in children aged 2 to 18 years.

DATA EXTRACTION

Two reviewers independently screened sources, extracted data on participant, intervention, and study characteristics, z-BMI/percent BMI, harms, and study quality using the Cochrane and Newcastle-Ottawa risk of bias tools.

RESULTS

A random effects model was used to pool the effect size across eligible 10 randomized controlled trials and 2 quasi-experimental studies. Compared with usual care or control treatment, brief interventions feasible for primary care were associated with a significant but small reduction in BMI z score (-0.04, [95% confidence interval, -0.08 to -0.01]; P = .02) and a nonsignificant effect on body satisfaction (standardized mean difference 0.00, [95% confidence interval, -0.21 to 0.22]; P = .98).

LIMITATIONS

Studies had methodological limitations, follow-up was brief, and adverse effects were not commonly measured.

CONCLUSIONS

BMI surveillance and counseling has a marginal effect on BMI, highlighting the need for revised practice guidelines and the development of novel approaches for providers to address this problem.
